A head gasket is a long-life component designed to maintain proper combustion sealing and prevent coolant/oil cross-contamination. This type of failure should not occur on a new vehicle and suggests a potential manufacturing or engineering defect in the powertrain. Before diagnosis, the vehicle displayed symptoms consistent with gasket integrity loss, including rough running, shaking during acceleration, reduced power output, inconsistent engine temperature, and abnormal vibration. These issues indicate possible combustion leakage, coolant intrusion into the cylinders, or compromised cooling system performance. Given the low age and mileage of the vehicle, the failure does not align with normal wear. Possible causes include improper factory installation, uneven torque application, defective gasket materials, engine block or cylinder-head surface irregularities, or thermal management issues that could cause localized overheating or warpage. Any of these would point to a systemic defect rather than owner misuse. A failing head gasket can lead to engine overheating, stalling, power loss, oil/coolant contamination, and eventual engine failure. These conditions present clear safety risks if they occur while the vehicle is in motion. Because this is a major powertrain failure occurring far earlier than expected, I believe this issue may affect other 2024 CR-V models and warrants investigation. I am submitting this complaint so NHTSA can review whether a potential defect exists that could require further action to protect consumers.","products":[{"type":"Vehicle","productYear":"2024","productMake":"HONDA","productModel":"CR-V","manufacturer":"Honda (American Honda Motor Co.)"}]}]}
